Switch between Lever type and Film type fuel sensors

<< < (2/2)

Unfortunately I cannot assist with your query.

I did the change from film to lever on my bike, which required the ZFE setting unit to be changed and it worked well. Process competed in 2 mins max, if that long.

If no other help arrives here, I suggest you contact the HEX team. Good luck.

botus:
you can ONLY move to a lever sensor if the bike has a ZFE High - aka a bike that came with ESA - it has additional logic programmed inside that is not there on the ZFE basic bikes

you also have to add more wires (better idea) or swap pin locations at the ZFE plug from strip to float inputs

a south american company is making an alternative better than BMW strip  https://www.fuelsensortech.com/en

a main issue trying to play with the strip is the error code only likes to clear if there is a working strip fitted to the bike.   There was no need to change the bike if it came with a strip and was getting a new strip - the calibration process can be done - but you don't code sensor type ever - I forget which is which but BMW naming is misleading and inductive sensor is usually the opposite to the one you think they meant

Hi,

So after a few weeks, i decide to go with the bike to the dealer. I load the bike on the trailer, for a 20 km and when i wanted to show them what is wrong there was no error more. That means that after a calibration and repalcement you must ride with the bike. Before that was the strip in the tank, full of gasoline fur sure more than a week and everytime whne i checked there was an error.
Also the GS 911 works good, the only thnigs that is happend in my case is that the procedure for change from strip to lever or from lever to strip was never ending with a message like by calibration that the procedure is done. Because i didnt get any message from GS 911 i thought that the change wasnt done succsefully.

So i learned something new.

I too have repeatedly had this problem. GS-911 WiFi June 12/24 update (although it did it last year multiple times with the previous update as well) It doesn't matter on what bike or platform. It happens with iPad, Mac, Windows PC There appears to be a software bug or some other issue. I successfully re-pinned the ZFE and switched via film to lever six months ago. However the float set up was not near as accurate as a strip. With the new improved BMW strip, as well as the FuelSensorTech strips, I decided to change back to film sensor. I re-pinned the ZFE back to OEM config -i'm very experienced at this I've done it on a number of bikes) verified zero resistance for all four strip sensor wires from CFE connector to fuel pump. As the OP stated, when you initiate the configuration change from lever to film, and follow instructions precisely, every time the GS 911 interface ask you to turn off the ignition, it gives the command "please wait before turning on ignition". The bar graph then countdown from 100% to approximately 40 to 50% once the ignition is off. It then hangs up there for hours and nothing happens. I made absolutely sure the 911 is not going into sleep mode and have a charger connected full-time always showing 13+ volts. I even left a PC set to never sleep on it overnight and the process never completes, as soon as you turn the ignition on or refresh the page, you get an error code and you never know if the recoding is complete. I then have the same problems as OP: fuel strip will not calibrate no matter what. (Two different strips are brand new and yes they are dry outside the tank and at room temperature)  Get a constant  "calibration error", strip real time values are all zeros except for 1MA Fuel Strip heater current. Bike does not recognize the strip at all. 2008 R 1200 RT. 100 mile ride with the strip with varying levels of fuel made absolutely no difference. Get constant "fuel level sensor implausible value" error.

I debrief this problem to the helpdesk last year as far as the fuel center configuration change function hanging up. Well it's still does it, again on all platforms, it appears that the coding change is not taking place in the ZFE. They ask you to turn the ignition off and to wait to turn it on and then nothing happens. All I know is my bike was working fine before as far as fuel sensor goes and now it does not appear to recognize any strip. Importantly: when I connect either of the brand new strips outside the tank to a 2009 R 1200 GS, the strips will calibrate immediately and real time values will all read normally. The problem appears to lie in the configuration lever to film function of the GS 911. Again I have double checked continuity and zero resistance between all four pins on both ends so it's not the bike. It feels like the coding was wiped and will not come back when I switch from lever to strip as the application just hangs. Any ideas? Any other experiences like the original poster; I'm crossing my fingers that maybe eventually it'll come back as was the case with him; I will debrief to hex desk. I have seen multiple others in different threads with the same problem and why it's still does it is a mystery to me. Unable to attach photos sorry for the long descriptions.
